摘　　要：目的研究淮北市地下水水质变化趋势,为水源保护和饮用水的监督监测提供依据。方法依据淮北市区域规划和工业企业区及居民区的分布,从北向南依次均匀布点36个,连续监测10年。用Grey-Markov趋势研究分析方法对变化较大的总硬度,氯化物、硫酸盐3项指标进行统计分析。结果 10年间淮北市市区岩溶水总硬度、氯化物、硫酸盐3项指标平均为376mg/l、39.9 mg/l、96mg/l,矿区集镇岩溶水为335mg/l、97.4mg/l、157 mg/l,浅层地下水为377mg/l、99.3 mg/l、121 mg/l。经分析不同区域和不同取水层的地下水3项指标的含量,均有随年份逐渐增高的趋势。其2011年的预测值市区分别为418.36mg/l、44.58mg/l、126.07mg/l;矿区集镇分别为404.11 mg/l、68.43 mg/l、135.49mg/l;浅层地下水分别为488.66mg/l、145.69mg/l、178.67mg/l。结论淮北市地下水水质在逐渐恶化,如果任由这种变化趋势长期存在,势必影响供水安全。Objective To study the developing trend of the quality of groundwater in Huaibei city,and provide the basis for the protection of water sources and the supervision and monitoring of potable water.Methods Based on Huaibei municipal regional planning and the distribution of industrial areas and residential areas,from north to south,36 monitoring sites were located equably and they were monitored continuously for ten years.Using Grey Markov Chain Model,three indices of large deviation were analyzed statistically,such as the total hardness,chloride and sulphate.ResultsThe average values of the total hardness,chloride and sulphate of karst water during these ten years were 376mg/L,39.9 mg/L,96mg/L respectively in urban area of Huaibei city,335mg/L,97.4 mg/L,157mg/L respectively in coal mine area.And these three incides of shallow groundwater were 337mg/L,99.3 mg/L,121 mg/L respectively.The result of analysis showed that the content of these three indices of groundwater in different areas and different depth of water level increase with the time gradually.The predictive values of these three indices in 2011 were 418.36mg/L,44.58 mg/L,126.07mg/L respectively in urban area,404.11mg/L,68.43 mg/L,135.49mg/L respectively in coal mine area.And the predictive values of shallow groundwater were 488.66mg/L,145.69 mg/L,178.67 mg/L respectively.ConclusionThe quality of groundwater in Huaibei city was getting worse gradually.If that continued,the safety of water supply would be affected inevitably.
